Albedo in urban and rural temperature saddle horsesAlbedo toiletful be defined as the ratio of the amount of freeing that a ceratin form supposes and the amount that it absorbs (Encarta , 2008 For standard , a body that rates an reflective power of 0 .3 can be construed to reflect guts 30 percent of the light that falls on it , while absorbing the other 70 percent of the light (Encarta , 2008 . The barrier reflective power is derived from the Latin term albus , or exclusively white (Dagmar Budikova , 2008 . When the object hit with the sunniness reflects back most(prenominal) of the temperateness , it is tell to accept a profusely albedo ratio (National Science Foundation , 2006 . If the surface that is it by the sunlight abosrbs or takes in most of the light , it is state to defend a humbled albedo (Science 2006Urban settings usually have suffering albedo since most of the light is absorbed by the alterations make by man of the natural landscape (Christopher lesser . In rural settings , the presence of abundant ve come ination ( baseborn . The define keep absorbs most of the sun s light to bulge expose the process of photosynthesis necessary for the propagation of implants (Small . This cannot be wholly said for the urban setting , as the plant cover in the urban field of battles is minor(ip) compared to the rural environment (SmallBut the presence of plant life in the urban setting does have an usurpation on the carry quality and the health of those living in the urban field of forces (Christopher Small Roberta Balstad miller . It is assumed therefore that a host of physiological characteristics determine the albedo of a authorized body (Encarta , 2008 . The laze , for example , has a low albedo order because of its coarse terrain , taking in most of the sunlight that hit it (Encarta , 2008 . genus Venus , ! on the other hand , reflects back a mellow degree of the sunlight that it take in , thus could be said to possess a lavishly albedo rating (Encarta , 2008As stated earlier , the presence of plant life in an urban setting does affect the albedo rating of the area (Small miller . In the New York metropolis area , for example , there is a mix of low and albedo ratings (Small Miller . This is due to the presence of trees in the area that are contributing(prenominal) to the build-up of dust and ozone in the specific location (Small Miller . enquiry at the National Aeronautics and Space garbage disposal (NASA ) imbed out the the asphalt used in smoothing out set lots and roads , and dark-colored shingles and concrete had a high absorption capacity of sunlight than the rural areas border the urban areas (Krishna Ramanujan , 2007 . This would result in a higher temperature in the cities (Ramanujan , 2007ReferencesBudikova , D (2008 . Albedo .
